This application claims the benefit of priority of European Patent Application No. 18205006.2 filed Nov. 7, 2018, the contents of which are incorporated herein by reference in their entirety.

TECHNICAL FIELD

The present invention relates to a method for broadcasting a message to the wearer of a watch.

The invention also relates to a watch implementing this method as well as a computer program.

PRIOR ART

In the prior art, the viewing of messages such as short, instant messages or emails, is conventionally carried out by a wearer of a smartwatch by viewing the contents of this message on a dial of this watch after a plurality of operations of manipulation carried out on the watch. However, such a mode of viewing these messages is not necessarily adapted to all the situations in which the wearer of the watch may find themselves namely the situations that imperatively require the use of their two hands.

To overcome this disadvantage, watches are known allowing to carry out a viewing of the contents of these messages via sound.

However a major disadvantage of these watches is related to the fact that such a viewing mode can lead to discomfort for the wearer of the watch when it disturbs the silence reigning in places in which it is imperatively required.

It is understood that there is thus a need to find an alternative solution, in particular which does not have the disadvantages of the prior art.

BRIEF DESCRIPTION OF THE DRAWINGS

Other particularities and advantages will be clear from the description thereof given below, for informational purposes and in no way limiting, in reference to the appended drawings, in which:

FIG. 1 shows a flowchart relating to a method for broadcasting a message to a wearer of a watch, according to an embodiment of the invention, and

FIG. 2 shows a watch implementing this method, according to the embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a method for broadcasting a message to a wearer of a watch. This method aims to notify/inform the wearer of the watch 1 for example of the contents of a message received and/or of the contents of a notification message, in a discrete manner that is to say without emission of a sound by a sound interface of this watch 1, and without it being necessary for the wearer to view the dial of their watch. It is noted that in this watch 1, the notification message comprises a content which can thus relate to an alert relative to the identification of an event relating to a function of the watch, this can for example be an alert relative to the reception of a short or instant message.

In this context, the message broadcast by the watch 1 to the wearer, namely via a touch-rendering interface 3, is a touch alert. Indeed, such an interface 3 allows the wearer to perceive the message by touch. In other words, the reception of this message by the wearer makes use of a touch sensory perception of the latter. In one example in which this message is a notification message, the wearer can perceive on their skin a sensation of a caress if the contents of the notification message relate to a missed call from their girlfriend or in an alternative, the wearer can perceive on their skin the realisation of a contour of the shape of a heart.

Such a method is implemented by a watch 1 namely a smartwatch illustrated in FIG. 2. Such a watch 1 comprises in a non-exhaustive and non-limiting way:

-   -   a processing unit 2 comprising physical and software resources         in particular at least one processor cooperating with memory         elements;     -   the touch-rendering interface 3 comprising a plurality of         vibrating elements 4 such as transducers capable of converting         an electric signal into mechanical oscillations (for example: a         plurality of piezoelectric elements;     -   a hybrid display dial 5 provided with a first analogue display         component and a second digital and/or alphanumeric display         component;     -   a sound interface 6 such as a speaker;     -   a communication module 7;     -   a mechanical or electronic movement 8, and     -   environmental, behavioural and/or physiological sensors 9.

This processing unit 2 of the watch 1 is linked/connected inter alia to the sound interface 6, to the touch-rendering interface 3, to the vibrating elements 4, to the display dial 5, to the communication module 7, to the movement 8 and to the environmental, behavioural and/or physiological sensors 9.

In this watch 1, the touch-rendering interface 3 is defined in all or just a portion of a part of the watch 1, said part being intended to be in contact with the skin of the wearer for example that defined at their wrist. In other words, this touch-rendering interface 3 can be comprised in/on a face for contact with the skin of the bottom of the watch case and/or on/in a face for contact with this skin of the wristlet. In a first example of realisation, the vibrating elements 4 of this touch-rendering interface 3 can be arranged on all or a part of an inner face of the bottom of the watch case 1. In a second example, these vibrating elements 4 can be arranged in the wristlet or in the contact face of this wristlet, in particular in at least one strand of this wristlet. It is noted in this example that the contact face of this wristlet is preferably deformable. In a third example, these vibrating elements 4 can be arranged in the contact face of the bottom of the watch case, this contact face preferably being deformable. In a fourth example, the touch-rendering interface 3 comprises a deformable support membrane in which the vibrating elements 4 are arranged. In this example, this membrane can thus be a part added onto the watch 1 by being fastened to the contact face of the bottom of the watch case and/or to the contact face of the wristlet. In one alternative, this membrane can be made in one piece with the contact face of the bottom of the watch case 1 and/or of the contact face of the wristlet.

It is noted that in this watch 1, each vibrating element 4 is distinctly linked/connected to the processing unit 2. Such a vibrating element 4 can for example be manufactured from a piezoelectric ceramic or from a flexible piezoelectric material (polyvinylidene fluoride—PVDF), and can have, in a non-limiting manner, a circular shape and/or be a film or a skin. Such a vibrating element 4 can have characteristic dimensions of approximately several square millimetres or even several square micrometres with a small thickness of approximately several millimetres or even several micrometres. In this configuration the processing unit 2 is capable of individually and/or distinctly controlling each vibrating element 4 of this touch-rendering interface 3.

In this watch 1, the communication module 8 is configured to establish a connection with a system of cellular networks by comprising namely a SIM card (acronym for “Subscriber Identity Module”) or with a system of WLAN wireless local networks, and is also capable of implementing communication technologies for example such as Bluetooth. In these conditions, the watch 1 is capable of exchanging data with a remote server, a computer or even a smartphone.

Moreover, the environmental sensors 9 of the watch 1, are specifically adapted for measuring environmental parameters for example such as the temperature, the atmospheric pressure, etc. With regard to the behavioural sensors 9, they are capable of measuring all types of behavioural characteristics of the wearer of the watch 1 for example such as the movements or the gestures carried out by the latter. To do this, these behavioural sensors 9 can comprise one or more inertial sensors of the accelerometer, gyroscope or miniature multiaxial gyrometer type such as multiaxial sensors manufactured using MEMS technology, capable of detecting angular speeds and linear accelerations according to a plurality of axes associating accelerometers and/or gyroscopes. With regard to the physiological sensors 9, they are capable of measuring the parameters relative to the functioning of an organism of the wearer such as, for example, the pulse, the saturation of the blood with oxygen, the impedance of the skin, the blood pressure, the respiratory rate, the respiratory arrhythmia, the skin temperature, the sweat rate, the saturation of the blood with oxygen or the blood flow.

Such a method comprises a step of reception 10 by the processing unit of data of information relative to a function of the watch. This watch indeed comprises a set of functions. These functions relate in a non-exhaustive and non-limiting manner to: the management of telephone calls, the management of short messages of the SMS or MMS type, the management of instant messages, the measurement of an atmospheric pressure, the measurement of an altitude, the measurement of a temperature, the providing of sports results, of navigation/guiding assistance, the measurement of heart rate, the measurement of number of steps, of calendar, of alarm etc.

In this context, the data of information comprises for example a set of descriptive characteristics relative to all types of communication media such as a short message, an instant message coming from social networks, an email or a notification message. With regard to the short message or the instant message, the data of information related thereto can be received from remote servers via the communication module. With regard to, the data of information relative to a notification message which results from the identification of an event relative to functions of the watch 1, it is received by the processing unit 2 from the sensors 9 of the watch 1 or from remote servers. In this context, it is noted that the identification of an event by the processing unit 2, can correspond for example to:

-   -   the determination of the exceeding of a threshold by a         measurement coming from one or more sensors 9 namely in the case         of monitoring by this processing unit of a behavioural or         physiological parameter of the wearer or of an environmental         parameter, etc.;     -   the reception of a missed telephone call received by the         processing unit 2 from the communication module 7;     -   the reception of a short or instant message or of a piece of         mail that is electronic and received by the processing unit 2         from remote servers via the communication module;     -   the activation of an operating mode of the watch 1;     -   a triggering of an alarm such as: an alarm for the alarm clock,         alarm for a meeting, alarm for taking a drug;     -   etc.

In these conditions, data of information comprises a set of descriptive characteristics relative to:

-   -   a short or instant message or an email can comprise:         -   a category of data of information, for example a short or             instant message or an email;         -   contents of the message, for example: text, image;         -   the time/date of reception of the data of information;         -   contact elements of the sender, for example: last name,             first name, etc.;         -   the profile of the sender, for example: family member, close             friend, work colleague, client, boyfriend/girlfriend,             spouse, etc.     -   a notification message can comprise:         -   category of the identified event, for example: alarm for the             alarm clock, alarm for a meeting, alarm for taking a drug,             missed call, new measurement of a behavioural or             physiological parameter of the wearer or of an environmental             parameter, etc.;         -   time/date of the identified event, for example: time of the             missed call, time of the measurement, etc.

In addition, it is noted that when the notification message relates for example to a missed telephone call or to the reception of a new set of characteristics relative to a short or instant message, these characteristics can further comprise:

-   -   contact elements of the sender/the caller, for example: last         name, first name, etc.;     -   the profile of the sender/the caller, for example: family         member, close friend, work colleague, client,         boyfriend/girlfriend, spouse, etc.

The method then involves a step of processing 11 of the data of information relative to the function of the watch. This step 11 comprises a substep of extraction 12 of at least one descriptive characteristic of said data, the substep 12 involving a phase of selection 13 of at least one descriptive characteristic in the data of information according to an extraction criterion. This extraction criterion is previously defined by the wearer of the watch 1 and comprises namely the number and the type of descriptive characteristic to be selected. Such a criterion thus allows to identify at least one characteristic to be selected out of the plurality of characteristics comprised in this data of information. For example, if the set of descriptive characteristics relates to a notification message relating to a missed telephone call from the spouse of the wearer, and the extraction criterion involves the selection of two characteristics, the first of which must relate to the category of the identified event and the second to the profile of the caller, then the characteristics extracted correspond for the first characteristic to “a telephone call” and for the second to “the spouse”. In another example, if the set of descriptive characteristics relates to a short message of the SMS type containing a text comprising only the term “bonjour”, and the extraction criterion involves the selection of three characteristics, the first of which must relate to the category of data of information, the second to the contents of this message and the third to a contact element of the sender, then the extracted characteristics correspond for the first characteristic to “short message”, for the second to “bonjour” and for the third to the first name of the sender “Tintin”.

Such an extraction criterion allows to define the descriptive characteristic(s) which participate in the design of the touch message to be broadcast to the wearer.

The method then comprises a step of sending 14 of a message signal relative to said data of information received, to the touch-rendering interface 3 of the watch 1, said interface 3 being configured to transmit said alert to the wearer of the watch 1. This step 14 comprises a substep of selection 15 of a criterion of design of the message signal on the basis of said at least one descriptive characteristic extracted from the data of information. This design criterion is defined according to one or more descriptive characteristics that are capable of being extracted from the data of information. This design criterion is preferably previously configured by the wearer of the watch like other design criteria archived in the memory elements of the processing unit 2. Such a design criterion comprises a scenario of operation of the vibrating elements forming the touch-rendering interface 3. This design criterion thus participates in the design of the signal relative to this message intended to be transmitted to the wearer of the watch 1. For example, if the first characteristic is “a telephone call” and the second “the spouse” of the wearer then the criterion for design of the signal comprises an operating scenario that aims to design a touch message specifically defined for these characteristics and the contents of which are those of a notification message which informs the wearer of the watch 1 through touch. This touch alert can correspond for example to a sensation of a caress perceived by the wearer or in one alternative to the realisation of a symbol/pattern on the skin of the wearer such as the contour of the shape of a heart. In another example in which the first characteristic is a “short message”, the second the term “bonjour” and the third the first name of the sender “Tintin”, then the criterion for design of the signal comprises an operating scenario that aims to design a touch message specifically defined for these characteristics and the contents of which are those of a short message which informs the wearer of its contents here the term “bonjour” and the first name “Tintin” which signs this touch message, for example by the realisation of the shapes of the letters of the words “bonjour” and “Tintin” on the skin of the wearer.

It is noted that when the message comprises a graphic representation such as an image of the emoticon type, the processing unit is capable of implementing a digital processing of this image in order to identify for example the main object of this image and define the essential shape thereof for a representation of this shape on the skin of the wearer.

The criterion for design of the signal comprises data on operation of the touch-rendering interface 3. More precisely, this data on operation of the touch-rendering interface 3 comprises at least one frequency and at least one amplitude defined for each vibrating element 4 forming said interface 3. In particular, this operational data comprises:

-   -   the duration of broadcasting of the touch message;     -   at least one time/period of operation of each vibrating element         4 with respect to the duration of broadcasting or:         -   a unique time of operation during all or a part of the             duration of broadcasting of the touch message, or         -   a sequence of times of operation during the duration of             broadcasting of the touch message, and     -   for each operating time:         -   a frequency of vibration and an amplitude of vibration, or         -   a frequency of vibration and a sequence of amplitudes of             vibration, or         -   a sequence of frequencies of vibration and a sequence of             amplitudes of vibration, or         -   a sequence of frequencies of vibration and an amplitude of             vibration.

It is noted that the sequence of frequencies of vibration can comprise only similar or substantially similar frequencies, or only different or substantially different frequencies, or a combination of similar and different frequencies. Likewise, the sequence of amplitudes can comprise only similar or substantially similar amplitudes, or only different or substantially different amplitudes, or a combination of similar and different amplitudes.

This step 14 then comprises a substep of generation 16 of the message signal on the basis of said design criterion. During this substep 16, the processing unit 2 designs on the basis of this design criterion, the message signal which allows to individually and/or distinctly control each vibrating element 4 of this touch-rendering interface 3. This signal is then sent by the processing unit to the touch-rendering interface 3 during a substep of transmission 17 of the signal. Such a signal comprises distinct control instructions of each vibrating element 4 during the duration of broadcasting of the touch message.

Upon reception of this signal, the touch-rendering interface 3 emits/broadcasts this message onto the skin of the wearer. Thus, this message can correspond in a non-limiting and non-exhaustive manner to:

-   -   the realisation of a contour of a graphic representation such as         a pattern/symbol, a letter, a number in a touch-based manner         that is to say as can be realised by the movement of the tip of         a finger of an individual on the skin of the wearer;     -   the application of the graphic representation onto the skin of         the wearer for example the application of the shape of a letter         or of a symbol/pattern;     -   the generation of a wave and/or vibrating phenomenon aiming for         example to create for the wearer a soft, pleasant, sensual or on         the contrary unpleasant perception.
